Our Tattoos

Ok so this story originally started as a one shot for my other book "Fluff and Smut {Destiel/Sabriel}". It was going to be the second one shot that became more than one chapter, but I didn't feel that was right. First off, it was nearly detailed enough. It didn't really make sense. Secondly, I have so many ideas on what to do with this story! I wouldn't really wanna write it all for just a one shot. I may break your heart at times (If I didn't I wouldn't be a true Cambion) but don't worry because it all ends happy!
So a bit of info on the story;
They all live in a world where some are lucky enough that one their 7th birthday, a magical tattoo shows up on their left forearm. The tattoo is of the first
their soul mate speaks to them. Then, when you meet your soul mate, the tattoo turns a shiny gold. If your soul mate dies, your tattoo will disappear. (hehehehe)
So what happens when Sam and Dean move to a new town called Heaven, and after just one day, their tattoos are gold? What happens when Dean starts off on the completely wrong foot with Cas? What happens when there is more than one possibility for Sam?
